Lawn pest control in Lakeland, FL addresses the insect species that damage Polk County turf grass: southern chinch bug (Blissus insularis) in St. Augustine, tropical sod webworm (Herpetogramma phaeopteralis) in St. Augustine and bermuda, southern mole cricket (Neoscapteriscus borellii) in bahia and bermuda, and a rotating cast of armyworms, billbugs, and white grubs. Lawn pest control is generally a separate license category (FDACS Category 8C) from structural pest control. Call the number below to be connected with an FDACS-licensed Category 8C lawn operator serving your Polk County address.
The four major Polk County turf pests
- Southern chinch bug. The single largest cause of St. Augustine grass death in Polk County. Damage shows as yellowing-to-brown irregular patches that expand in sunny areas. Peak damage May–September.
- Tropical sod webworm. Larvae feed at night on leaf blades, leaving notched and chewed edges. Damage spreads quickly during summer warm fronts.
- Southern mole cricket. Tunneling damage in bahia and bermuda. Surface ridges and uprooted seedlings. Active spring and fall; nymphs do most of the damage.
- Fall armyworm. Episodic outbreaks late summer through fall. Can destroy a lawn in 48 hours during heavy population events.

Lawn pest control vs. general pest control
FDACS regulates these as separate license categories. Category 8C (Lawn and Ornamental Pest Control) covers turf insect, disease, and weed management. Category 8B (General Household Pest Control) covers the structural pests inside and around the home. Many Polk County operators hold both licenses and offer combined programs, but a Category 8B-only operator is not licensed to perform lawn insecticide work.

Frequently asked questions
How do I know if my Lakeland lawn has chinch bugs?
Yellow-to-brown irregular patches in sunny areas of St. Augustine grass during May through September are the diagnostic. Confirm with a ‘float test’ — cut a coffee can open at both ends, push one end into the soil at the patch edge, fill with water, watch for chinch bugs floating to the surface.
Are lawn sprays safe for my dog?
Pets stay off treated turf until the spray has dried, typically 30 to 60 minutes. Granular formulations are safe once watered in.
Will lawn treatment hurt beneficial insects?
Properly applied lawn pest treatments target soil-level and thatch-level pests. Pollinator-active flowering weeds and ornamentals are avoided. Bti larvicides (Bacillus thuringiensis kurstaki) are used selectively for caterpillar control where pollinator concerns are high.
Can I combine lawn pest control with my structural pest program?
Yes. Many Polk County operators write combined programs covering both Category 8B (structural) and Category 8C (lawn) work.
